title: Small-cell lung cancer (SCLC) cell adhesion on E- and P-selectin under physiological flow conditions.
abstract: Hematogenous metastasis is still a poorly understood phenomenon. The rate-limiting step within the metastatic cascade is not yet clear although it may be estimated that the extravasation of circulating tumor cells is a step of crucial importance, as most tumor cells that are shed into circulation undergo apoptosis. The process of extravasation includes a cascade of consecutive steps, starting with adhesion of tumor cells circulating in the bloodstream to endothelial cells, mimicking leukocyte adhesion and transmigration. Endothelial cell selectin-leukocyte glycan interaction occurs when leukocytes adhere to endothelial cells under conditions of shear stress. As there are parallels between cancer cell endothelial interactions with leukocyte endothelial cell systems an experimental setup has been developed in which adhesion of small cell lung carcinoma adhesive properties can be analyzed under physiological shear stress conditions during their attachment to E- and P-selection.
